摘 要：
鸟类的体重与适合度密切相关。然而,目前国内对鸟类体重的季节性变化报道相对较少。利用河南董寨国家级自然保护区鸟类环志的数据分析棕头鸦雀(Paradoxornis web~bianus)体重的季节性变化规律。2006~2012年间,董寨鸟类环志站在保护区范围内共称重4 530只棕头鸦雀,分属于除1月和7月以外的其他各月。数据分析发现,棕头鸦雀全年各月的体重均值(W±标准差)在(9.6±0.9)g~(11.2±0.7)g之间,棕头鸦雀在春季(3月开始)体重下降,初夏时(6月)有一定增加,然后又降低,至秋季(10月)开始上升,至冬末(次年2月)达到最大值。棕头鸦雀体重的季节性变化规律可能与其繁殖和换羽等生活史周期有关。

摘 要：
The body mass of birds is closely related to their fitness.In this study,we investigated seasonal body mass variation of vinous-throated parrotbill(Paradoxornis webbianus) in Dongzhai National Nature Reserve,Henan Province.From 2006 to 2012,a total of 4530 individuals were banded and measured at Dongzhai Bird Banding Station,during all months except January and July.Their mean(±SD) body mass varied from(9.6 ± 0.9) g to(11.2 ± 0.7) g in one year.Body mass was lower in spring(starting from March) and increased in early summer(June).After another drop in summer,body mass increased in autumn and peaked in winter.This pattern of body mass variation was possibly related to portions of the life history cycle such as breeding and moult.
